From the Editor.
The year has certainly gone quite quickly and 2015 is not that many sleeps away.
In 2015 as you may have read Queensland will host the Nationals in Brisbane with the Free
flight competition being seperated to be contested at Dalby in May 2015.
The Nationals calendar of events is in this edition but by logging into the MAAA web site- www.
maaa.asn, will give you access to the entry form on line and any updates.
The event calendar for next year is slowly filling with events. I would encourage the clubs to
get their events in early to avoid clashes particularly when clubs are in close proximity to each
other.
I thank those clubs and special intrest groups who were able to contribute to this edition of airflow at late notice. With out their contributions this newsletter would not have been printed and
would have been postponed until the new year.
Finally I would like to thank our advertisers who have supported the newsletter over the past
year and to the contributors who make the content, along with the cover designer Jim Henry
who really makes the cover come alive.
In closing,on behalf of the MAAQ Committee I would like to wish a Merry Christmas and a
prosperous New Year to all the readers, members and their families.

Model Building at the Southern Downs Flexible Learning Hub
November 2014
This last term, 9 students have been active in both building a RC aircraft kit and learning to
fly using the Warwick Aero Modellers simulator and club trainers. With the time spent on the
simulator, these students are picking up the flying training very well, as it shows when the
students take their turn to take hold of the transmitter.
Last term MAAQ were generous in their provision of a grant to support the delivery of this
program at the Southern Downs Flexible Learning Hub (SDFLH). This grant enabled the
purchase of 9 kits, covering for most of the models and servo’s to share between the finished
models. The model we are building is HobbyKings Cloud Dancer. This is of traditional
construction of interlocking balsa and ply and is to date, building rather quickly. Some of the
parts require considerable patience to remove from the sheets as the laser cutting has some
imperfections. The instructions called for CA to be used predominantly, but as SDFLH is a school
risk assessment procedures were implemented. I called Alistair at Christian Traders to see if
he could assist with some ‘mates rates’ prices on some of his Deluxe glues. After explaining
the nature of SDFLH and its students, he very generously DONATED ALL the glues that we
would require. If you’re not familiar with the Deluxe glues, have a look at his advertisement in
this newsletter on his website, as there are water-based alternatives to CA that are much more
student-friendly, if you know what I mean… They work well too.
The first step in flying training involved proving to me that they can safely keep an aircraft off
the ground and make it go in the chosen direction using WAM’s simulator. The next step was
buddying up with me using WAM’s Boomerang 60 with a 10cc Evolution Petrol engine, flying at
the club’s field. This is an ideal trainer, as it is BIG and doesn’t get too small too quickly and it
flies for 50 minutes without landing on the fuel it carries. We have also flown smaller aircraft at
the school, but due to trees, it isn’t ideal. Next year we will be focusing on improving their flying
skills. Time constraints prevented regular flying training this year using a real model and we have
only managed 3 flying sessions at the WAM club field.
I would like to thank the MAAQ and Christian Traders for their generous support in promoting
building and flying Radio Controlled model aircraft at the SDFLH. The students are getting a real
buzz out of it, especially the flying part.

Successful first aero tow of the Seagull model of the KA8 at TARMAC Aero Tow Day
This three metre model is an almost ready to fly (ARF ) that has been carefully put together with
some modifications done to ensure better flying ability. Upon checking incidences it was found
that the tailplane leading edge needed to be raised some 6 mm.
The tailplane seat was built up to suit and two longer tailplane bolts were used along with new
blind nuts under the ply seat. 5 mm of wash out was put into the tips along with the addition of
electric scissor type spoilers have been added and a graupner type tow release in the nose.
Quarter scale horns and better quality clevises were also substituted with the bolt thru the surface
as the kit supplied horns were a glue in type into a shallow 6.5 mm hole in each surface. The balsa
was quite soft particularly in the ailerons so the area was hardened under the covering with thin
cyno before the horns were installed.
With most ARF models it pays to check the glue joints particularly in wing joiner boxes ,engine
mounts and in the construction in general.
This model was not too bad but I had decided to go over them with a brush and thinned down weld
bond to all joints particularly in the fuse where the wing meets the fuse.
By carefully drilling a hole in the front nose former inside I was able to fill the nose with lead shot
to get the balance right. The first flight revealed that the balance was 5 mm to the rear (set at 65
mm as per the directions) which made elevator very sensitive.
By shifting the balance point further forward to 60 mm has settled this down.
Note that the balance point should be at 60 mm from the leading edge and not 65 mm.
I think the project was well worth the time to get a nice flying model from these modifications.

New F5J Electric Glider Event Takes Off!!
In 2011 the FAI approved provisional rules for a new electric glider
competition that does not require a fast climb; it puts the emphasis on finding
thermals and staying in them. Interest in the event has taken off world-wide.
In Australia, NSW has lead the country in trying the new event with many
events being held around Sydney, Goulburn and Canberra.
The AEFA has adopted the event for all its large rallies. Up to 20 fliers attend these events
and interested spectators come from far and wide to check out the new event.
You no longer need a high-powered electric glider to compete. The aim is a
200m climb or less within 30 seconds and then to fly out a 10 minute working
time. Only a gentle climb is required and many electric gliding enthusiasts
have had to detune their set-ups. Rob Watson from the Macquarie club
encouraged everyone by placing in many events with a Radian, foamy, 2m
glider. A simple glider can do well if you can find thermals!
The event is scored on the total flight time, less the penalty for how high you
climbed, plus a modest spot-landing bonus. In practice, the length of the
flight is the most critical aspect, the height you climbed is a secondary
consideration, and the event is certainly not decided by spot landings.
So, how do we know what height you achieve in your climb? And how do we
make sure your motor turns off at 30 seconds in to the climb? Enter the Alti
#2 Basic and Multi 2 height limiting devices and data loggers. The original
unit was designed to switch your motor off at a pre-determined height or
after a certain time had expired. This unit was then modified with new
firmware to record the height achieved in the climb and to turn the motor off
after 30 seconds.
A hand-held device called an RC FXJ Programming Card was also
developed to use with these. The programming card has been modified to
read out the climb height after your flight has been completed.
The Australian Electric Flight Association promoted the event by purchasing
a collection of these devices and a few hand-held readers, so that fliers could
come to an event without a device and still take part â&#x20AC;&#x201C; they are loaned out for
the day. These are still available, but many fliers now have their own devices,
and the AEFA runs a monthly postal competition where fliers log their own
flights and submit the results to a central point and a winner for the year is
declared.
Since then many more devices have become available. One of the most recent
is the Altis V.4, which has an LCD display on the device itself, so you do not
need a hand-held reader.
You launch your aircraft as the hooter sounds the beginning of the 10 minute
window. You can switch off at any time up to 30 seconds in to the flight.
Some brave fliers have even tried switching off at 50m when they perceive
thermal activity! If you keep running your motor, it will be automatically
stopped by the device after 30 seconds and you must not start it again. Some
devices do not allow a restart, but more recent ones allow a restart in an
emergency situation with a zero score being recorded in an event,
AIRFLOW 11

but the aircraft can be saved! You then try to land right on the spot landing marker
just as the 10 minute hooter sounds.
The hand-held device is plugged in to the Alti #2 Basic or Multi 2 when you
land and it reads out the height gained during the motor climb. See the
photograph showing Rob Watson taking a height reading with Steve Mutch’s
sailplane.
F5J is also scheduled for the Sailplane Expo in Armidale in January. So, you
can see that the event is catching on in Australia. Ian Avery from the Nowra
club, who came to witness one of the Picton trials, has suggested that two
classes be introduced in the F5J – a standard class for smaller gliders and an
open class for larger gliders. This has been adopted, and awards are now
given at each event for Open F5J and for <2.5m F5J (for gliders with less
span).
Interestingly, Glider Score software developed by Gerry Carter in Melbourne
is being used all over the world to score this event. Gerry’s software will score
any glider event, but an F5J segment has been added to the program and
modified following feedback from overseas. It is now the international
standard fro scoring.
The F5J event is now popular in many overseas countries. Slovakia has
developed a web site to publicise international events in F5J. You can see
details here: http://www.rivamodels.sk/f5magazin_en.html
To see the rules for the new event, look on the AEFA web site at:
www.aefanet.com
There are also reports on the Australian events of F5J on the AEFA site; click on the
newsletter links.
This new F5J event is being offered at the 2015 MAAA Nats to be held in
Queensland. The event is scheduled for Thursday 18 April at the MRSSA field at
Harrisville – see the Nats schedule of events.
Dust off your electric gliders and join in the F5J revolution!

Queenslanders joined Victorian and New South Wales free flighters, plus a number of
R/C and C/L flyers from various NSW clubs to celebrate a momentous occasion for
Australian free flight - the opening of Australia’s first and only free flight field owned by
the flyers. Thanks to the foresight of the NSWFFS and the extreme generosity of Jo
and Adrian Bryant, free flight modelers no longer have to worry whether free flight will
continue in Australia, as fields become unavailable or cut up for development.
The West Wyalong field is located in central west NSW, 15 hours from Brisbane, 5 hours
from Sydney and 6 hours from Melbourne. For those who have been to Narrandera, it’s
less than 2 hours north. It is a flat 700 acre field 1.9 km x 1.4 km, with short grass, is easy
to walk or ride on and has minimal trees - in other words, an excellent free flight field.
Situated in sheep country, it is not suited to cropping, and that made it affordable. Crops
and free flight aren’t a good mix. A large portion of the field is leased to a nearby farmer
to keep some sheep on it – and that provides a reasonable income. It also it keeps the
grass down!

SATURDAY: A good role up of flyers and spectators arrived early, including MAAA
secretary Kevin Dodd. Once the flight line was established, it stayed that way for the
day. Two quad bikes joined the few electric bikes of those who preferred not to walk.
Saturday was a magnificent day with clear skies, good lift and minimal breeze from varying
directions. Soon there were all sorts of models in the sky - vintage, scale, sporties,
power and rubber and a few gliders. Flyers were aged from 7 to 94 years. There were
three competitions but the mix of models made it great for the spectators. A few limited
function R/C models flew discretely among the F/F models including a magnificent 4 m
R/C electric glider.

AIRFLOW 17

Failed DTs resulted in some big times. 12 min 45 sec flight from Albert Fathers’ Open Rubber
Waif, and over 20 minutes for John Corby’s model although Terry Bond also went big - over
30 minutes. All models were recovered undamaged, two less than 400 metres away! From
Peter Jackson’s 0.24cc sport to Roy Summersby’s .46 powered Playboy, the air seemed
full of models. The Dixielander contest was spear-headed by the fast climbing Rothwellpowered Dixies, with Vin Morgan’s “electronic throttle” Dixie outfoxed by the speedy climb
from Des Slattery’s early lightweight OS-powered model. The Open Rubber event had some
upsets - notably that of top NSW flyer Jim Christie failing to score three maxes. Des, Leigh
Morgan and Albert didn’t fail, so they made up Sunday’s fly-off trio.
Saturday flying comps ended by 3.30 pm and we adjourned to the newly placed runway and
control line circles, to watch some R/C and C/L flying. The runway is behind the house and,
when we got there, it was just like discovering another flying field, in the “back paddock”.
This property is really big and most F/F flyers would be happy to fly 2 minute events from
this part of the field. The R/C boys loved it and a small group flew there both days. And now
the NSWFFS is getting requests from other clubs to run R/C events there in the future. This
of course could happen in conjunction with a free flight competition; there is plenty of room.
West Wyalong has REAL potential for developing into an aeromodelling centerpiece.

AIRFLOW 18

Come 6 pm Saturday, NSWFFS president Terry Bond officiated at the Grand Opening and
the speeches were well received. Understandably, the biggest cheer was for Adrian Bryant
who will go down in Australian Free Flight history for his extreme generosity for backing the
field financially. Adrian also responded to Terry’s speech and later cut the cake with his and
Jo’s name on it. Jo passed away recently; she was very supportive of the field purchase.

Many years ago, Adrian was treated for an infection and an overdose of antibiotics left him
with negligible balance. He was to be confined to a wheel chair but his perseverance saw
him at flying fields, moving with the aid of a gnarly walking stick made from a tree branch.
We nicknamed him Gandalf, from Lord of the Rings! It should be known that for over 10 years
Graham Maynard and Albert Fathers took Adrian from Queensland south to all the major
events. Albert went one step further, taking Adrian to the local Coominya FF field, helping
him compete and retrieving his models. This was a selfless contribution on Albert’s part –
and it kept Adrian involved in what he loved.
During the evening, MAAA secretary Kevin Dodd also awarded Roy Summersby his Hall of
Fame award for his first place in the F1C world champs in France last year.
SUNDAY: Saturday was perfect and Sunday was “more perfect”, as the flight line remained
in the middle of the paddock all day, and there was virtually no breeze in the morning. The
Open Rubber fly-off commenced at 7.30 am with Des Slattery putting in his best launch ever.
Albert Fathers was away next getting higher than Des but the prop fold was bad, caused by
a new tight motor. This turned a 7 minute flight into something half that, as the model glided
left instead of right. You could easily see the attitude and descent rate didn’t look good for
Albert. Leigh Morgan launched last and her glide was almost good enough, losing 13 secs
to Des and clearing Albert by a mere 2 secs. All three models landed less than 300 m away.
AIRFLOW 19

Mid-morning we were surprised to see a Jabiru light aircraft land on the new R/C runway,
proving yet again the field is of adequate size. It later successfully took off. Turns out they
were friends of an R/C flyer.
Vintage Rubber was a surprise, with most models dropping one or more rounds. Howard
Gostelow flew a Vagawock but soon moved to his more reliable Senator. Don Broughton,
with his model on trim, looked good. Albert Fathers’ Boxall model failed to unwind a knot
well behind its CG, pock marking the covering as it tried to do so. Dave Bailey’s rocket climb
was so impressive and threatening but the stand-out was Adrian. With his “pit crew” of eager
helpers and his chrome plated “old person’s” chair, Adrian wound and launched precisely,
three times. He normally only puts in one celebratory flight per competition these days but he
was encouraged to endure three flights. And that he did very well, maxing all three, with two of
these not even needing bonus points. It was so good to see him win, and you could see in his
eyes he thought the same way!

By midday the contests were over and the awards were presented, so ending a superb
weekend of flying and comradery. The West Wyalong field will evolve into a premier flying site
for southern hemisphere free flight, radio control and control line. I’m sure of that.

Thermal Scout - A Prototype is born by Mike Chapman UK
I built a prototype exactly to my plan, two coats of non-shrinking dope were given, the scales
showed that it had an all-up weight of 16 grams. An evening test session at the local park lasted
for about an hour, flights with Thermal Scout were mostly above 35 seconds and the best was
49 seconds. I had thought before the test session, that upon completion I would probably have
to redesign part of the model but that wasn't the case. I immediately built another Thermal Scout
for myself.
Building
To save the Scouts time and balsa wood I made templates to mark out the wing / tail / fin shapes
onto the wood and roughly cut out 25 of each.
I made up about a dozen sanding blocks from the left overs of the 3/16 sheet. Modelling knives
were a problem as the cost prohibited me from providing one per scout. The same was the case
with the balsa planes, I had bought one plane for the Scouts and I also took along my own .
I had tried to anticipate the problems I would encounter with 25 Scouts all of whom had no experience of handling Balsa / modelling knives and reading plans. But after the first session with the
lads (now 26 of them) my head was in a complete spin. The simple fact is that they will all start
building together and all (some more than others ! ) will want help in some form or other and the
questions come thick and fast. A two hour building session seemed to pass in about 15 minutes !
The availability of a blackboard was very useful, any anticipated problem areas were illustrated
using coloured chalks. These were changed as we progressed through different stages of building.
Before each session I used the blackboard for a 'pep' talk to clarify the forthcoming building techniques.
There were some accidents during the building stage, all of which I was able to rectify by gluing
or reshaping, in a few cases I had to issue new blanks.
The biggest surprise to me was the amount of non-shrinking Dope that the lads were able to
make disappear ! - where it went I don't know - but I needed twice as much as I had anticipated !
Flying the Thermal Scout
It took three evening sessions to complete the gliders and on the fourth evening we went along
to the local sports center to fly the models. A quick distribution of plasticine (modelling clay) and a
demo of how to trim the glide and they were away. (I had provided diagrams but no one seemed
to have read them !)
The quality of the flights varied but everyone had a model that flew and all the Scouts had showed
great enthusiasm throughout.
The Scouts were particularly enthusiastic when I demonstrated my Hybrid competition model. I
can see now the field full of circling and whirling Scouts, yelling and shouting as they chased after
it - they didn't realise it would circle around !
In total I think we built about twenty six models and that was from materials intended for twenty. If
you should have the opportunity to organise such a project, do so, it's good fun and promotes the
sport of aeromodelling, also in this case each scout was awarded a Craft badge.
Finally I also gave the lads a pile of my old modelling magazines to use as a 'library' - you never
know !

AIRFLOW 21

Building Instructions
Start by cutting out a ‘kit’ of parts.
Cut out the wing in one piece - plane and sand it to shape before cutting at the centre and then
rejoining with Epoxy (50mm dihedral each tip).
Cut out the tailplane and fin, sand their edges to about .5 mm thickness, leave the centre 4 mm
of the tailplane untouched (flat) as it will be glued to the underside of the fuselage.
Cut the fuselage from 5 mm balsa sheet (hard), cut it accurately as there is incidence built into
the wing seat. If you measure the wing seat position (on the fuselage) you will find that the rear
of the wing is 1 mm lower than the front.
[More experienced builders will perhaps like to build up the fuselage as follows:- From the bottom up - 1.5 x 5mm spruce strip, 5 mm x 5mm hard balsa strip, the upper part of the fuselage
can be Medium/Soft grade balsa. This method will result in a strong/stiff/ light fuselage.]
Before sanding the rear of the fuselage to an oval section, glue (Cyano’) the spruce strip to the
bottom of the fuselage. It is shown on the plan as 2 x 5 mm but 1.5 x 5 mm will suffice. Round
all the edges of the fuselage.
Join the wing to the fuselage with Epoxy glue.
Before fitting the tailplane sand the bottom of the fuselage rear end to accommodate the tail tilt
(3mm). Use Cyano’ glue to attach the fin and tailplane. Ensure that the fin is vertical.
Cut the finger grip from 5 mm balsa - bevel and taper to fit the underside of the right hand
wing - ensure a good fit between the wing and fuselage as this will impart added strength to
the wing / fuselage joint.
Finish the model with 2 to 3 coats of non-shrinking dope, sand with fine ‘wet and dry’ paper
between coats.
Test Flying
Build your model exactly to the plan, the scales should show an all-up weight of around 16
grams. A visit to the local field (with long grass) will be required for testing, calm evenings are
the best times for first flights.
Using Plasticine stuck to the nose, an initial balance point at around 50% of the wing chord
should be established. Check also that neither wing is heavier than the other - add a little plasticine tip weight to balance if necessary. Test glide using shallow gentle hand launches, add or
remove Plasticine until a flat shallow glide is achieved.
Once a flat glide is established - ensure that the model is also turning to the left. If it is not
then gently bend the rear of the fin to encourage a left turn. When all is correct Thermal Scout
should be launched up at an angle of about 40 degrees and to the right of the wind (in your
face). Launch by trotting forward a few steps and use a whipping arm action to launch.

In the next edition of Airflow, a plan of a popular glow/deisel free flight model turned into
R/C electric powered model suitable for NEFR old timer events.

Ray Baines recently completed project, it looks stunning and he had this to say about it..
â&#x20AC;&#x153;What a great day !!
Well I took my recently completed PA-25 Pawnee to the field this morning for a test flight.
What a Beaut !!!
Darn thing took off like a homesick angel....
The DLE 35 was just perfect at half throttle and only small trim changes were needed.
She is going to be a real keeper !!
The model spans 96 inches and takes me back to the farm with memories of being doused with
2-4-D as a young lad. Those pilots were my heroes as I watched them work the paddocks and
then land back to reload at a polo field on a neighboring property . All great fun !!
Hope to catch you at the field soon.â&#x20AC;?
